To run an FCS platform, people with three different levels of privileges are needed. In order to understand these levels, we would like to begin by giving a short explanation.

There are 3 levels of privileges in the hierarchy:

• System administrator ("S-Admin"):
  The system administrator assigns one ore more platform administrators ("P-Admin") to each platform.
  
  
• Platform administrator ("P-Admin"):
  The platform administrator provides each user group with access and/or publishing rights for particular services.
  
  
• Users:
  Users set permissions for the content ("facts") they create.

If factline acts as an application service provider (ASP), the system runs on a server powered by factline. In this case, factline takes over the tasks of the S-Admin.
